Chiral Separation Medium

技術優勢: The invention also provides methods for preparing the enantioselective separation medium and electrochromatographic devices fabricated therewith.

技術應用: This invention relates generally to the field of electrochromatographic separation, and more particularly relates to a novel enantioselective separation medium comprised of a monolithic, chiral, ionizable copolymer.

*Abstract: An electrochromatographic device is provided for conducting enantioselective separation of enantiomers. The device is comprised of a conduit containing a monolithic enantioselective separation medium, and may be, for example, a capillary tube or a microchannel in a substrate. The enantioselective separation medium is prepared by copolymerization of (a1) an ionizable chiral monomer or (a2) a chiral monomer and an ionizable comonomer, along with (b) a crosslinking comonomer and (c) a polymerization initiator, in (d) a porogenic solvent. Following ionization, the enantioselective separation medium serves as a charge carrier as well as a chiral separation medium, and further acts as an electroosmotic pump to facilitate the flow of a fluid. The invention also provides methods for preparing the enantioselective separation medium and electrochromatographic devices fabricated therewith.
